Thiago Santos is in good spirits and on the comeback trail following extensive surgeries stemming from his loss to Jon Jones at UFC 239.

Santos (21-7 MMA, 13-6 UFC) managed to push UFC light heavyweight titleholder Jones (25-1 MMA, 19-1 UFC) to the brink earlier this month in a five-round fight that resulted in a split decision win for Jones. It was clear “Marreta” hurt himself early in the fight, but managed to go the distance with the champion.

After the event, it was revealed Santos has suffered a thorough amount of damage to his left knee. The immediate diagnosis was a torn ACL, MCL, PCL and meniscus. Upon further review, he was deemed to have meniscus damage in his right knee, as well.

“After 4 hours of surgery, the drs say everything is fixed! Now my focus is on a full recovery so I can get back in there better and stronger!”

Santos, 36, did not provide an updated timeline for his return to competition. MMA Junkie previously reported he is expected to be out until at least mid-2020, and already there are calls for a rematch with Jones.
